However, in the conventional monitoring technology, when the elevator control cabinet fails, the functions cannot be continuously executed.
In order to improve the system defects, the invention provides an elevator fault remote monitoring device which can perform remote monitoring when an elevator control cabinet fails, and the system composition can be understood by combining fig. 2 and 3.

In the elevator trouble remote monitoring device according to embodiment 1 of the present invention, the data transmission means 6 may be a wired network or a wireless network, and may be implemented as data transmission means in the above device as long as data transmission and reception are possible. For example, the cable transmission network based on the modem has low implementation cost, low power consumption, simple configuration and use, supports parallel multi-data channels, and works in real-time online and on-demand online modes, can ensure the safety and reliability of data transmission, and can use the cable network based on the modem as a data transmission unit.

With the existing elevator remote monitoring apparatus structure as shown in fig. 1, usually the elevator control cabinet 02 and the remote monitoring apparatus 03 are centrally supplied with power from the main power supply 05. When a power failure occurs, namely, a circuit for supplying power to the elevator control cabinet 02 and the remote monitoring device 03 by the main power supply 05 is disconnected, even if an independent storage battery is installed on the remote monitoring device 03, the elevator control cabinet 02 can still continuously operate during the power failure, but the power source of the power supply portion 022 of the elevator control cabinet 02 is shut down, so that not only is the remote control of the elevator difficult to realize, but also the running state information of the elevator stored in the elevator control cabinet is lost during the power failure.
In order to avoid the above situation as much as possible, as shown in fig. 2, the elevator trouble remote monitoring apparatus according to embodiment 1 of the present invention further includes a power supply device 34 during power failure. When a power failure occurs, the power supply line of the power supply device 34 for supplying the operating power to the elevator control cabinet 2 and the remote control device 3 during the power failure constitutes a backup power supply circuit. Specifically, the power supply device 34 includes a backup power source 341 and a backup circuit switch 342 as shown in fig. 3 at the time of power failure. The backup power source 341 is disposed on the backup power supply circuit, and the elevator control cabinet 2 and the remote control device 3 are electrically connected to the backup power source 341 through the backup power supply circuit, respectively; a standby circuit switch 342 is arranged on the standby power supply circuit; the backup power source 341 is electrically connected to the elevator control cabinet 2 through the backup circuit switch 342; the processing unit further comprises a trigger switch 335 for sensing the on or off state of the first power supply circuit; the first power supply circuit and the standby power supply 341 are electrically connected to the remote control device 3 through the trigger switch; when the first power supply circuit is in an off state, the trigger switch 335 connects the circuit of the backup power source 341 to supply power to the remote control device 3; the processing unit controls the standby circuit switch 342 to close and the standby power source 341 simultaneously supplies power to the elevator control cabinet 2. Therefore, when the supply of the first power supply circuit is interrupted, the first power supply circuit can be quickly switched to the standby power supply circuit through the trigger switch, the remote control device can continue to be powered on to keep the working state, the standby circuit switch is controlled to be closed through the processing unit, the standby power supply circuit is communicated, and the electric energy supply of the standby power supply to the remote control device and the elevator control cabinet is realized. For the trigger switch 335, a circuit interlock mode can be set to connect a power supply loop between the standby power supply and the remote control device through an interlock unit of the trigger switch when the first power supply circuit is disconnected, and for the detection of the state of the first power supply circuit, a current signal on the first power supply circuit or a main power switch on-off signal can be detected, when the trigger switch senses a preset power-off state, the remote control device can send a control signal to drive the standby circuit switch on the standby power supply circuit to be closed, so that the uninterrupted operation of the elevator control cabinet and the remote control device during power failure is realized, and the remote monitoring and control of the elevator are continuously implemented.
In practice, the backup power source of the backup power supply circuit is generally a storage battery, and the battery capacity is limited, and if the backup power source is continuously operated, the capacity is completely discharged, and a long time is required for the power source to be supplied and recharged again. In order to improve the reliability of the backup power supply and prevent the backup power supply from being unusable during a blackout, the elevator fault remote monitoring apparatus provided in embodiment 1 of the present invention further includes a charging circuit for charging the backup power supply 341 during a call, wherein in actual implementation, the charging circuit is communicated with an external power supply (for example, the main power supply 5 in fig. 3), and the backup power supply 341 is electrically connected to the charging circuit. A charging circuit switch 352 for connecting or disconnecting the charging circuit is arranged on the charging circuit; the charging circuit switch 352 includes an open state and a closed state; when the first power supply circuit is switched from the off state to the on state, the trigger switch 335 may open a loop (for example, in a circuit interlock manner) in which the standby power supply 341 supplies power to the remote control apparatus 3, the processing unit controls the standby circuit switch 342 to be switched off and the charging circuit switch 352 to be switched on, and the charging circuit is switched on, that is, the standby power supply may be timely supplemented with electrical energy when an incoming call comes. Specifically, in fig. 3, a circuit formed by electrically connecting the main power supply 5 and the backup power supply 341 through the charging circuit switch 352 is referred to as a charging circuit in embodiment 1 of the present invention. The charging circuit switch 352 and the backup circuit switch 342 both perform an on/off function for the power supply circuit, and may be switches provided on the backup power supply, or may be switch units provided on the charging circuit and the backup power supply circuit, respectively.
